Is there a way to automate loading csv files in Paraview?

I am using Paraview to display well log information stored in csv files.

Upon loading the csv data file and adding the "Table to Points" filter, I manually specify which columns should be used for the X Column, Y Column and Z Column (e.g. I am using a column called "Easting" for the "X Column").

Is there a way to automate this step? Maybe some kind of configuration file that could be fed into Paraview to indicate the column mapping?

You can use python macro to do that. Macros in ParaView are python script you can trigger from the toolbar.

You can use this one to create and configure a TableToPoints filter (with modif according to your column names):

#### import the simple module from the paraview
from paraview.simple import *
#### disable automatic camera reset on 'Show'
paraview.simple._DisableFirstRenderCameraReset()

# create a new 'Table To Points'
tableToPoints1 = TableToPoints(registrationName='TableToPoints1')

# configure column names
tableToPoints1.XColumn = 'y1'
tableToPoints1.YColumn = 'y2'
tableToPoints1.ZColumn = 'y26'

# get active view
spreadSheetView1 = GetActiveViewOrCreate('SpreadSheetView')

# show data in view
tableToPoints1Display = Show(tableToPoints1, spreadSheetView1, 'SpreadSheetRepresentation')

# hide data in view
Hide(sineWavescsv, spreadSheetView1)

# update the view to ensure updated data information
spreadSheetView1.Update()

Store it on your disk and go to menu Macros / Import new macro

Note that you can easily create your own with the Python Trace:

  1. menu Tools / Start Trace (with default options)
  2. perform the actions you want to replay later (load file, create filters, edit color map, ...)
  3. Tools / Stop Trace. It opens an editor with python code, you can save it as a macro.
  4. The macro is a new button in the toolbar.
